This project aims at the development of a pre-commercial prototype software for cochlear implantation -- surgical procedure to restore hearing in patients who suffer from medium to severe hearing loss -- to achieve more predictable and controlled interventions. CIPlanner is a surgical planning software for specialists to computationally predict the outcomes of the intervention for a given patient according to a set of implant and surgical parameters. It provides computational results that support pre-operative decisions, such as the optimal implant position, and help hearing professionals to guide the post-interverventional procedure by providing the most favorable setting for the patient.
